This page lists changes between different editions of WALS Online. While no longer accessible
online, the data of older editions could be computed using the changes listed here. If you
need a full database of an older edition this may prove cumbersome, so in this case

Other changes

There are two new chapters (chapter 143 on Order of Negative Morpheme and Verb, and
chapter 144 on Position of Negative Word With Respect to Subject, Object, and Verb,
both with many new maps)

Additional features have been added to some chapters.

The genealogical classification of languages, including genera, has been updated.

The one-to-many relationship between chapters and features/maps is now clearly reflected
in the structure of WALS: A single chapter can contain not just one feature, but several
features, most often two (e.g. feature 39A and feature 39B), but sometimes (with the new
chapters 143 and 144) quite a few features and maps.

For some of the features, WALS now includes examples supplied by the authors (for example feature 113A)

WALS Online now contains the long introduction chapter of the printed atlas from 2005
